Article Synopsis
  • The study investigates the effects of atmospheric reactive nitrogen (Nr) deposition on Chaohu Lake, a eutrophic lake in eastern China, which is prone to algal blooms, highlighting the limited research on this topic, especially in lakes primarily receiving nitrogen from rivers.* -
  • In 2022, the total nitrogen input from river sources to the lake was 11,553.3 tons, with atmospheric deposition contributing 2,326.0 tons, making atmospheric Nr deposition an essential factor in the nitrogen burden of the lake.* -
  • The findings suggest that atmospheric Nr is a significant source of bio-available nitrogen, accounting for 24.5% of total nitrogen inputs, indicating that efforts to combat eutrophication should

Background/objective: Cervical cancer is the major cause of cancer-related mortalities in women globally. It constitutes one of the life-threatening conditions for women in developing countries. The popularization of cervical cancer screening and the improvement of treatment levels has caused the mortality rate of cervical cancer to decrease gradually, but pelvic floor dysfunction before and after cervical cancer treatment has become prominent and attracted more and more attention.

Photodynamic therapy (PDT) utilizing Hematoporphyrin Derivative (HpD) injection has been demonstrated as an efficacious treatment for various conditions, including Bowen's disease, subtypes of basal cell carcinomas, and actinic keratosis. While surgical resection is considered the primary treatment option for extramammary Paget's disease (EMPD), some patients may not be suitable candidates for surgical intervention. ALA-PDT may have some benefits in treating EMPD in select patients, while Hematoporphyrin Derivative-Photodynamic Therapy (HpD-PDT) has demonstrated promising potential as a cancer treatment.

Based on the suppressor of cytokine signaling 1 (SOCS1)/Janus kinase (JAK)/signal transducer and activator of transcription 3 (STAT3) pathway, the mechanism of oxymatrine in the treatment of atopic dermatitis (AD) was preliminarily explored in this study. C57BL/6 mice were induced to establish AD model by smearing carbotriol (MC903) on their back. The AD mice were randomly divided into model group, oxymatrine groups with three dosages (25, 50 and 100 mg/kg), ( = 10).

Article Synopsis
  • Nitrogen oxides (NO, NO2, and NO3) are key atmospheric components affecting ozone and radical formation, and tracking their emissions is important for understanding nitrogen cycles.
  • Existing methods for collecting nitrogen isotopes from NO for analysis are inefficient and slow, making it difficult to analyze low concentrations in clean areas.
  • The introduction of a 3D-printed honeycomb denuder (3DP-HCD) system significantly improves collection efficiency (up to 70 L/min) and provides reliable isotopic data, enabling detailed studies in pristine environments.

Increasing evidence suggests the essential regulation of RNA N6-methyladenosine (m6A) modification in carcinogenesis and immune response. Nevertheless, the potential impacts of these modifications on the tumor microenvironment (TME) immune cell infiltration characteristics in clear-cell renal cell carcinoma (ccRCC) remain unclear. Utilizing a consensus clustering algorithm, we determined three m6A modification patterns and identified three m6A-related gene clusters among 569 ccRCC samples, which were associated with different biological functions and clinical outcomes.

Neurogenic lower urinary tract dysfunction (NLUTD) is a common urological disease that causes long-term complications and severely reduces patient's quality of life. Sacral neuromodulation has proven to be an effective treatment for NLUTD. However, most previous studies have focused mainly on the efficacy and safety of sacral neuromodulation in the treatment of NLUTD and less on the changes in urodynamic parameters in patients before and after sacral neuromodulation.

Background: Signet ring cell carcinoma (SRCC) is a rare but highly malignant variant of bladder carcinoma. Nomograms have demonstrated good accuracy in predicting the prognosis and guiding the management of pure urothelial carcinoma (UC). However, no accurate and applicable nomogram has been formulated for primary SRCC cases.

Background: Bladder cancer (BLCA) typically has a poor prognosis due to high relapse and metastasis rates. A growing body of evidence indicates that N6-methyladenosine (m6A) and long non-coding RNAs (lncRNAs) play crucial roles in the progression of BLCA and the treatment response of patients with BLCA. Therefore, we conducted a comprehensive RNA-seq analysis of BLCA using data from The Cancer Genome Atlas (TCGA) to establish an m6A-related lncRNA prognostic signature (m6A-RLPS) for BLCA.

Growing evidence suggests that the tumor microenvironment (TME) plays crucial roles in tumor progression and treatment efficacy in clear cell renal cell carcinoma (ccRCC), which typically has a poor prognosis due to high relapse and metastasis rates. We comprehensively analyzed ccRCC RNA-sequencing data from The Cancer Genome Atlas (TCGA) database to identify candidate prognostic TME-related genes involved in ccRCC. We used the ESTIMATE and CIBERSORT algorithms to estimate the proportions of immune cells, stromal cells, and tumor-infiltrating immune cells (TICs) in the TME in ccRCC samples from 539 patients.

Increasing evidence suggests that N6-methyladenosine (m6A) and long non-coding RNAs (lncRNAs) play important roles in cancer progression and immunotherapeutic efficacy in clear-cell renal cell carcinoma (ccRCC). In this study, we conducted a comprehensive ccRCC RNA-seq analysis using The Cancer Genome Atlas data to establish an m6A-related lncRNA prognostic signature (m6A-RLPS) for ccRCC. Forty-four prognostic m6A-related lncRNAs (m6A-RLs) were screened using Pearson correlation analysis (|R| > 0.

The relationship of platelet-to-lymphocyte ratio (PLR) and survival in urological cancers remained inconsistent in previous studies. Therefore, we performed a meta-analysis to assess the prognostic significance of PLR in patients with urological cancers. A literature search was performed in the PubMed, Embase, and Web of Science up to July, 2017 and study quality was obtained using the Newcastle-Ottawa Scale.
